Gelation mechanism
WebMechanics of gelation describes processes relevant to sol-gel process . In a static sense, the fundamental difference between a liquid and a solid is that the solid has elastic resistance against a shearing stress while a liquid does not. Thus, a simple liquid will not typically support a transverse acoustic phonon, or shear wave. WebGelation is an important functional property of globular proteins (e.g., soy proteins) commonly used in the food industry. However, studies [7-10] showed that several factors …

WebDec 1, 2001 · A feasible mechanism of age gelation is based on a two-step process; in the first step, the beta kappa -complexes dissociate from the casein micelles due to the breakdown of multiple anchor sites ... WebUltraviolet-visible (UV-Vis) spectroscopy was used to track the change in Cat during the reaction process as a method to investigate the gelation mechanism. For HA-Cat, the quinone peak (λ max = 395 nm) appeared immediately after the addition of NaIO 4 , indicating the rapid oxidation of Cat in the presence of oxidants ( Fig. 2A ).
